A new monoraphid diatom species Tseplik, Kulikovskiy, Kociolek & Maltsev, is described from Indonesia. The species is described on the basis of molecular and morphological analyses. According to molecular data the new species belongs to the clade that includes strains of , and . Morphologically, the new species differs quite significantly from other species of the same genus because of linear-elliptic valves with almost parallel sides and strongly radiate striae and a butterfly-shaped fascia on the raphe valve. The morphology and phylogeny of the new species are discussed, and thoughts on the current state of the taxonomy of the genus are expressed. Our work shows the importance of using molecular data in diatom systematics and also demonstrates the need to investigate rarely studied regions of our planet.
一种新的单壳缝硅藻物种——泽普利克硅藻(Tseplik, Kulikovskiy, Kociolek & Maltsev),是在印度尼西亚发现并被描述的。该物种是基于分子和形态学分析来描述的。根据分子数据,这个新物种属于一个进化枝,该进化枝包含[具体物种名称未给出]、[具体物种名称未给出]和[具体物种名称未给出]的菌株。在形态上,这个新物种与同一属的其他物种有显著差异,其壳面呈线性椭圆形,两侧几乎平行,具强烈放射状条纹,且在缝脊壳面上有一个蝴蝶形的横沟。文中讨论了新物种的形态和系统发育,并表达了对该属分类学现状的看法。我们的工作表明了在硅藻系统学中使用分子数据的重要性,同时也证明了对地球上很少被研究地区进行调查的必要性。
